Hello,
Earlier I was having one shared module in the project for sharing between iOS and Android

But when I created another shared module. The iOS Header and Protocol files started to have ModuleName appended as Prefix to each class and protocol for iOS

Does any one know what's the reasoning behind prefix and how to get rid of it?

[Matthias Geisler]

You can write a GradleTask which makes the adjustments to __attribute__...there are also libraries like this one, but I am not sure if they are up to date.

[Rohan Maity]

Oh did not know about __attribute__
Let me look into the attribute, I hope this gradle task would be trivial to write
BTW do you have any example for this

[Matthias Geisler]

Sure...I did in one of our projects: https://github.com/d4l-data4life/hc-data-donation-sdk-kmp/blob/main/data-donation-sdk/build.gradle.kts#L247

[Rohan Maity]

Great !! Thanks @Matthias Geisler

Do you mean that you have a dependency from the ios exported kmp module to another kmp module?

[ade]

if that is the case, you can have kmp not generate prefixes by setting the export flag like so

val ios = listOf(iosX64(), iosArm64(), iosSimulatorArm64())
configure(ios) {
       binaries {
           framework {
               baseName = "mykmp"
               export(project(":moduleA))
...

you will also need to change the dependency from implementation to api in the dependencies block

[Paul Woitaschek]

That attribute thing should not be necessary. Properly exporting is the way to go

no nothing is exported from iOS

[Rohan Maity]

Its regular shared module only

[Rohan Maity]

Just in my case, there are two shared modules

[Paul Woitaschek]

You can't have different kotlin runtimes. It's always one umbrella Module where the framework is created

[Rohan Maity]

I am not sure about your framework statement

I was able to create two framworks and xcode is also able to detect it as well.

Only the Prefix module name is the issue as I mentioned earlier

[Paul Woitaschek]

How did you do that?

[Rohan Maity]

I followed the same pattern of shared module
Just repeated the same for second shared module

And did the ./gradlew build after that it was able to generate the framework for both modules

[Paul Woitaschek]

Ah, don't do that. You will have two kotlin stdlibs and native runtimes. That will greatly increase size and affect performance. I didn't even think this was possible

[Paul Woitaschek]

Create one iOS umbrella Module, and export both of them as shown above

[Rohan Maity]

Oh ok, now Understood the above code

[Rohan Maity]

It is including other module and exporting is one

[Paul Woitaschek]

Well either one includes the other and exports or you have a third umbrella one

[Rohan Maity]

Hmmm, but I kinda need the second module to be shared with other android app 🤔

[Paul Woitaschek]

But how is that an issue?

[Rohan Maity]

Oh yeah my bad I could share it as aar

[Rohan Maity]

🥲 missed this thing

[Rohan Maity]

But that export thing is a great help

[Rohan Maity]

Really appreciate it

[Paul Woitaschek]

Usually sharing is done through a maven repo

[Paul Woitaschek]

We use gitlab and every project has a maven repo where we publish the builds.

[Rohan Maity]

It is kinda pet project . So did not think of maven repo 🤔.
Glad to know this. Will try for this then

[Paul Woitaschek]

You can also add it as a git submodule and use includeBuild

[Rohan Maity]

Have not used submodules yet. It seemed complicated to me at first site. But it was also 3 years ago when I was in sophomore year
Hmmm

[Rohan Maity]

One more question, with the export , the module which I have to export, how can I refer that in xcode?

Or would it be available under the module for which framework is generated?

[Paul Woitaschek]

It will be in the framework with the name of your framework
